THRASHING-VIACHINE.

SPECIFICATION forming part of Letters Patent No. 491,485, dated February7, 1893.

Application filed March 28,1892. Serial No. 426,760. (No model.)

To all whom it may concern- Be it known that 1, WILLIAM M. KOPPES, acitizen of. the United States, and a resident of Orrville, county of'Wayne, State of Ohio, have invented a new and useful Improvement inThrashing-Machines, of which the following is a full, clear, and exactdescription, reference beinghad to the accompanyingd rawin gs, makingpart of this specification.

My invention relates to improvements in thrashing machines, and consistsin providing in a thrashing machine and a part thereof, a feeder andband cutter, the parts so arranged that the straw so fed will pass overand under an overshot thrashing cylinder, from which it will be carriedto the front end of the machine, when it will be turned, and carried outat the rear end of the machine by the vibrating tables providedtherefor.

With these ends in view, my invention relates to certain features ofconstruction and combination of parts, as will be hereinafter describedand pointed out in the claims.

Figure 1. of the accompanying drawings is a side elevation showing theform of the n1achine frame and casing. Fig. 2. is a longitudinal,vertical, sectional view showing the interior of the machine. Fig. 3. across section of Fig. 2 on line oc w. Fig. this a perspective of afragment of the band cutter shaft and one of the cutter heads. Fig. 5,is a plan view of the cutter comb.

Letters of reference indicate corresponding parts in all of the figuresof the drawings.

Side timbers or frame pieces, A, B, and O, which are horizontal and invertical order, form the principal; support for the various vibratingand rotary parts of the machine. The thrashing cylinder D is supportedas shown on the frame piece C, under the cylinder is placed a toothedconcave E; these parts may be of any of the well known and approvedforms.

To feed the sheaves to the thrashing cylinder, cross shafts a a arejournaled to the side boards F, on which is mounted flanged pulleys bI). About these pulleys b b is placed an open or slatted carrier G,which receives its driving power from the shafts a a, the top part ofthe carrier to move toward the cylinder D. The lower part to form a raketo draw the straw to the front end of the ma chine as hereinafterexplained.

Under the upper side of the carrier is placed a floor c, which serves asa support for the carrier. Above and over the carrier the cutter shaftH, is journaled to the side boards F, as shown, on which is mounted aseries of cutter heads J, having band cutters cl secured in an outwardlyprojected flange portion, the cutter to rotate in a direction oppositeto that of the cylinder. At the rear of the cutter heads is provided acomb e the slits thereof correspond with the band cutters d; this combserves to hold the straw down, and from following the movement of thecutters. Above and to the rear of the band cutter, cross shafts ff arejournaled to the upper portion of the side board F, on which is mountedflanged pulleys g g about which is placed a short open auxiliary carrierbelt or compressor K, which serves to compress or hold'down and feed thestraw to the cylinder.

Under and to the front of the thrashing cylinder, and carrier G, isprovided a vibrating frame L, which is supported on hangers h as shownin Fig. 1; at the top of said frame is a perforated table L, under whichis provided a grain table L having a raised center '5, forming sides j,that slope downwardly and outwardly toward the sides of the machine, asshown in Fig. 3. Under the rear end of the carrier G, is placed a guideplate 70, and to the side of the concave, an extension grate 7a whichtwo parts form a throat, through which the straw passes from thethrashing cylinder, on to the table L, and under the carrier Gr. By thejoint operation of the table L and the under side of the carrier G,forming the rake M, the thrashed straw is moved forward and dumped intothe front end of the machine onto the vibrator N, by which it is turnedand carried or tossed rearward onto a similar vibrator O, by which it istossed rearward and out of the machine. The vibrators N and O, aresupported on links Z at their rear ends, and on cranked shafts Z attheir front ends, by which the said vibrators are operated to agitatethe straw to shake out the thrashed grain, and to move the strawrearwardly and out of the machines, the grain falling upon the grainboardsm by which it is conducted to the cleaning riddle n. The vibratortables N and 0, may be of any of the well known and approved forms ofconstruction. The thrashed grain that falls from the thrashing cylinderor table L,

'onto the table L, will be carried by gravity hereinbefore describedthat is a thrashing machine having incorporated therewith, and therein,a feeder and band cutter which is essentially a part of, and, whollywithin the structure, and for the movement of the thrashed straw fromthe rear to the front of the machine, thence back over the vibrators andout of the machine, whereby a more perfect separation of the grain fromthe straw may be had, and thereby a great saving.

By referring to Figs. 1 and 2, it will be noticed that the band cutterand feeder are constructed entirely within, and become a part of asingle structure comprising a sheaf carrier, aband cutterand acompresser or feeder, and a thrashing mechanism and separator, supportedby the same frame and inclosed by the same siding and deck.

In operation sheaves are placed on the carrier G, at each side of thedividing board P, and are carried under the cutters (Z by which the bandis severed, the cut sheaves are fed to the top portion of the thrashingcylinder by the united operation of the carrier G, and compressor orfeeder K, the straw and grain passing over the cylinder, and throughbetween the cylinder and concave, through the throat formed by the plateand grate it, onto the table L, under the rake M, formed by the lowerpart of the carrier G, by the joint operation of which the straw iscarried to the forward end of the machine, and thrown down onto thevibrator N, by which it is moved rearwardly to vibrator O, by which itis thrown out of the machine. The thrashed grain, passing through thegrate it and perforated table L to the table L and thence to the grainboards on. The grain that passes with the straw from the table L will beshaken out by the vibrators N and O and fall to the grain boards ashereinbefore stated.

Any suitable means may be provided for imparting to the grain table andseparators, a vibratory motion. For instance, to impart such motion tothe grain table, links L may be connected to the hangers h and a pulleyon the shaft a. And to impart a similar motion to the separators, a beltL may be engaged with pulleys secured to the ends of the cranks Z, and asecond belt L engaged with one of these pulleys and driven by power fromany suitable point. 7

Having thus fully described the nature and object of my invention, whatI claim as new and desire to secure by Letters Patent is:

1. In combination, a thrashing cylinder, an endless carrier to conveythe sheaf to said cylinder, a grain table located beneath said carrierin close relation thereto, whereby the straw from said cylinder will beraked over said table by the under side of the carrier, substantially asset forth.

2. In combination, a thrashing cylinder lo cated at the rear end of themachine, and endless carrier extending from the front end of themachine, to said cylinder, a vibratory table located beneath saidendless carrier in close relation thereto, a grate extending from theconcave of said cylinder to the said table whereby the loose grain isseparated and allowed to fall through said grate and the straw rakedover the table by the under side of the endless carrier.

3. In combination, a thrashing cylinder, an endless carrier, a bandcutteryand an auxiliary carrier or compressor consisting of an endlessslatted belt located above the first named carrier, and adapted to forceor hold down the bundles after the band has been severed.

4. In combination, a thrashing cylinder, an endless carrier therefor, atraveling auxiliary carrier or compressor located above the same,

a band cutter located in advance of said auxiliary carrier orcompressor, a table located beneath said endless carrier in suchrelation that the return side of the endless carrier will come incontact with the straw from the cylinder and rake it over said table,vibrating separator having its end inclined upward whereby the st rawafter leaving the front end of the grain table will be carried from thefront of the machine to the rear thereof and a grain board locatedbeneath said separator, substantially as set forth.

5. In combination, a thrashing cylinder, endless carrier therefor, aperforated grain table located beneath said carrier, a second tablelocated beneath the perforated table and composed of ribs inclining fromthe center to the sides of the said tables, means for vibrating saidtables, vibratory separators located beneath said tables, and a bandcutter, substantially as set forth.

In testimony whereof I have hereunto set my hand this 19th day of March,A. D. 1892.
